Abstract:
The NF-kappaB family of transcription factors plays a crucial role in the immune, inflammatory and apoptotic responses. These proteins are normally found in the cytoplasm, retained by interaction with an inhibitory molecule called IkappaB. Activation of the NF-kappaB signalling cascade results in phosphorylation and degradation of IkappaB, allowing nuclear translocation of the NF-kappaB complexes. The recent identification of a high-molecular-weight complex containing two kinases and a regulatory subunit has led to a flurry of new results that shed light on some of the most complex mechanisms contributing to the exquisite regulation of NF-kappaB activity.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
